        Mitigation of Voltage Fluctuations/Voltage Flicker and Power Quality Improvement in Power Systems Using Distributed Satcom

        Abubakar Sufyanu

        This paper deals with power quality and more specifically, voltage flicker in power systems. Voltage flicker is one of the disturbances in power systems. This flicker mainly occurs due to nonlinear loads. The magnitude of the voltage flicker solely depends on the type of electrical load that is producing the disturbance. Voltage flicker can also occur due to voltage sag and/or voltage swell in the system. This voltage sag can generate inrush current and this current passes into the sensitive loads in the distribution system.

            Transportation is one of the sectors that contribute to Greenhouse Gases (GHGs) emissions. In recent years, many efforts have been made to reduce Carbon Footprint (CF), particulate emissions, and cost of operation. Dual fuel technology has proven to be a viable technology since Compressed Natural Gas (CNG) becomes largely available. Nowadays, CNG is the best fuel alternative for the automotive industry, specifically for marine engines, heavy machinery, trucks, and buses for public transportation. This paper describes a novel approach to fuel consumption reduction and the optimization of the cost of operation after dual-fuel CNG-Diesel conversion for a fleet of 39 buses. A reduction in carbon Dioxide (CO2 ), emissions are reported with a reduction in smoke emission and Particulate Matter (PM) by equipping buses with an active PDF catalyst system whereby oxides of nitrogen (NOx), Hydrocarbons (HC), and Carbon monooxide (CO) emissions were 10% lower than the limits set by Japan’s current emission standard (JP05). Results were focused on the mixed fuel economy optimization using the best configuration of the CNG ratio map to be loaded in the Electronic Control Unit. Moreover, the range of the buses was increased, hence reducing stall time at pump stations. Finally, the study shows the financial advantages of diesel-engine conversion to the CNG-Diesel dual-fuel engine.
